Dredging on the lower Monongahela River has progressed to river mile 31, Pittsburgh District of the U.S. Army Corps of Engineers said in their latets project update.
Two cranes perform production dredging on 12-hour daylight shifts. A third crane is being utilized to dredge under bridges and powerlines.
Dredging is necessary to accommodate pool changes and maintain navigable waterways, said USACE.
The work on the lower Mon dates to a 1992 feasibility study that recommended turning two navigational pools into one and replacing or removing aging infrastructure.
The project is on track to be completed by late summer 2021 at mile marker 24.4.
